One of the defining features of cast iron is its ability to retain and distribute heat evenly. This characteristic is crucial when grilling, as it ensures that every part of the food cooks uniformly. Uneven heat can lead to burnt spots and undercooked areas, making the final meal less than ideal. A cast iron tray eliminates such concerns; with its thick bottom and sturdy build, it holds heat exceptionally well, allowing for a consistent cooking temperature. Whether you're grilling meats, vegetables, or even fruits, a cast iron tray guarantees that every bite tastes just as good as the last.
